风力发电机噪声传播的数值仿真
Numerical Simulation of Noise Emission of Wind Turbines
摘要
Abstract
The problem of wind turbine noise emission and propagation is discussed, and the mathematical relationship between noise intensity and distance is formulated. Since the noise recipients are generally located on the ground, the distance from the recipient to the wind turbine tower can be regarded as the independent variable to analyze the characteristics of noise propagation. Then, the noise is predicted numerically using software Cadna A. Results of mathematical derivation are compared with the simulation results, and both results are found to be in a good agreement.关键词
